Magnificent!! This is the largest species of dragonfly in Japan and, at 10cm long, it’s an impressive sight. This one was zooming around a clearing and it flew just above my head several times before settling on a remarkably convenient perch — convenient enough for me to sneak up and take lots of photos. I was amazed at how tolerant he was of me and I managed to get within about 50cm before he flew away. A few fly-bys later he settled back on the exact same plant so I took even more photos. I loved the way he cleaned his big green eyes with his forelegs — he’s got to keep his eyes clean to hunt on the wing.

Cyrtarachne inaequalis

What a cute and unusual thing to find — a natural smiley in the forest!! I couldn’t decide what it was at first as it was only about 8mm across. I was just thinking it might be a young snail when it suddenly dropped off the leaf on a silk thread. Oh, a spider!! It’s a kind of orb-weaver spider and its Japanese name means that it looks like a bird dropping. It should be called the Smiley Spider instead.

I often see these big black and white weevils hanging onto leaves like a cross between a koala and a (very small) panda! They walk very deliberately and drop off the leaf when disturbed. I think they are among my favourites.

I think somebody has made a bit of a mistake here! Take a closer look…

It’s remarkable how these Japanese beetles skeletonize leaves — they’re little artists really!!

These huge katydids (bush-crickets) are everywhere at the moment. They sit perfectly camouflaged on leaves and then half jump, half crawl into the foliage making so much disturbance that it’s like a much larger animal is lurking there. Once you get used to spotting them before they disappear, it’s possible to sneak up and take photos.

Such a beautiful weevil… but my photos are very poor. The evening was setting in and I was among trees and the weevil was only 3mm long… If I find one again, I will catch it and take the photo in a well-lit place to show off the metallic gold and green.

I stood taking photos of these hornets for quite a while but I think I should have been able to take better shots than these. I’ll try again next time. I guess there were 7 or 8 of them flying around and there’s a possibility I was nervous… Nah, I was fine. That’s just an excuse for poor photography!!

Jumping bristletails are primitive wingless insects that are thought to have been around 390 million years ago.

Today was Longhorn Beetle day for me! I went out for 4 hours between downpours and walked around my local area to see what I could find. Everywhere I looked I spotted longhorns: 9 species in total. Not bad. Well, just to put that figure into perspective… there are about 800 species of longhorn beetle in Japan!
